Enable Intel 82579LM NIC in VMware ESXi 5.0

We have just bought a new server with Supermicro X9SCL-F motherboard for our backup server. This server comes with 2 NICs:

Intel 82579LM Gigabit

Intel 82574L Gigabit

Unfortunately, once the hypervisor installation completed, only one network interface is detected by VMware ESXi 5.0 which is Intel 82574L port. Since our architecture required to have 2 different cards so we can use it as fault tolerance to bring high availability features.
